The extraction of organomercury(II)(RHg+, R; ethyl, n-propyl, n-butyl, phenyl) with 8-quinolinol into benzene has been studied by means of spectrophotometry. This study confirmed that there was no co-extraction of electrically neutral species RHgOH by its investigation of the effect of the pH on the extraction of ethylmercury(II) chloride into benzene. Moreover, it was found that RHg+ forms 1:1 complexes

Organomercury(II)(RHg+, R; ethyl, n-propyl, n-butyl) forms two kinds of water-soluble complexes, RHgq and RHg(q)(OH)−, with 8-quinolinol(oxine Hq). These complex-formation reactions are studied by means of spectrophotometry, and the formation constants of these complexes, RHgOH, RHgOAc, and RHg(OH)(OAc)−, in 4%(v/v) ethanol at the ionic strength of 0.1 are determined. Reliable results are obtained
有机汞(II)(RHg+,R;乙基,正丙基,正丁基)与8-羟基喹啉(oxine Hq)形成两种水溶性络合物RHgq和RHg(q)(OH)-。这些配合物形成反应通过分光光度法进行研究,这些配合物 RHgOH、RHgOAc 和 RHg(OH)(OAc)− 在 4%(v/v) 乙醇中,离子强度为 0.1 时的形成常数为决定。乙基汞 (II) 和正丙基汞 (II) 配合物获得了可靠的结果。
